acters. Let's try them and see what the difference is.
The following table shows the control codes for getting into
and out of double-strike and emphasized modes.

Run this program. The results will look like this:
THIS IS DOUBLE-STRIKE PRINTING
THIS IS EMPHASIZED PRINTING
AND THIS IS BOTH AT ONCE
Line 10 turns on double-strike with (ESC) "G" and line
20
prints a line of text. In line 30 double-strike is turned off with
(ESC) "H" and then emphasized is turned on with (ESC) "E".
Line
40
prints a line of emphasized text. Line 50 then turns dou-
ble-strike back on so that line
60
can print in both at once. Finally,
line
70
turns both off, so that Delta is set for normal printing.
Look closely at the different lines of printing. In the line of
double-strike printing each character has been printed twice, and
